Specification of Letters Patent.

Patented Feb. 26, 1907.

Appiimio'n nea June 7, 190i.V serai No. 211,454.

' State of New'York, have invented certain new and useful Improvements in Locating- Gages for Sewing-l`vlachines, of which the tollowing is a specilication, reference heing had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in sewing-machine attachments, and particu larly to neans arranged in connection with a sewing-machine for locating or positioning My device is preferably made in the form of an attachment which may be readily secured to existing forms of sewing-machines and in the preferred form is further so constructed that it may be turned out of the way `when not in use.

The main object of my invention is to provide nleans whereby the position of the material to te operated upon may te quickly and accurately determined, so that the material may he readily inserted in proper position in the work-clamp; and to this end niy inven tion consists in providing a locating means and suitable adjustments therefor, so that the saidv locating means may te properly po? sitioned-with respect to the stitching inechanism of the sewing-machine.

My invention also consists in providing the device with a suitable graduated scale, so

that the proper position ol the locating nzeans With respect to the stitching` nechanisni or work-support may lze quickly determined in an improved construction, wherebythe device may le readily thrown out ot position when not required to le used, and in certain novel details ot' construction and coinl ination of parts, as will hereinafter more l'ully appear. y

l. will now proceed todeserile a device einbodying niy invention and will then point out the novel leatures'in clainis.

In the drawings, ltigui'e l is a top view of a gage embodying iny invention, showing the sane secured to the led ol a sewing-machine and showing certain portions of the sewingmachine, including portions of lthe work clamp. Fig. 2 is a view invertical longitudinal section throughthe gage. Fig. 3 is avertical transverse section therethrough the plane of section being taken substantially upon the line 3 3 of liig. 1. Figa is a top view of the locating means removed from its carrier. Fig. 5 is a top view-in detail of certain parts of the gage, showing a ditl'erent form oll locating device employed and showing a piece-of fabric engaged thereby. Fig.

6 is a view in vertical transverse vsection thereof, the plane of section being taken substantially upon the line 6 6 of ltig.v 5.

rThe device herein may he employed as a gage for locating many articles; but it is especially adapted for locating collars in buttonhole-sewing machines when presented therein for the stitching of the central or back buttonhole. buttonhole be accurately positioned with respect to the end buttonholes, and heretofore It is essential, of course, that this a common practice has been to double over a collar and mark the center at the crease and to' then locate the collar in the worleclanp by means of this mark. lt will he readily understood that great inaccuracies often result from. such a custom.

In the preferred form of my present device, and which form is shown in Figs. l, 2, 3, and 4 of the drawings, T employ a locating means which-actually engages the collar by entering one ol the end huttonholes. It will then be seen that the said locating means heing initially adjusted to a predetermined position the collar will always be accurately centered in the work-clamp. By then providing the device with a graduated scale, the graduations oi whiclicorrespond to the difl'erence between the standard size of collars, it will he readily seen that the simple adjust nient oll the locating means along the scale will lne all that is necessary to accurately adinst the device l'or any size collar desired to he operated upon. l also preferahly provide two other ad |ust1nents,Mone a compensating adjustment, ol the locating means with respect to the scale, so that when the device is lirst set in the machine the relationship of the scale with respect to the point ol' stitching may he properly determined, and the other a lateral adjustment lor the device as a whole, so as to properly. position the worli laterally.

Referring lirst to Figs. l, 2, 8, and 4, l designates-a plate or clamp adapted to be se cured to the bed 2 of a sewing-machine, to

which it may he clamped by means el? asaid plate. The slot 4 permits the clamp or plate 1 to be moved laterally in order to laterally adjust same, the screw being employed for clamping it in the position to which it is adjusted. lreferably the iront edge ot the clamp or plate 1 is'provided with a flange 5, which engages the front edge of the bedplate 2 oi? the machine, whereby the plate may be prevented from turning. 6 designates a support pivoted to the clamp by means of a pivot-pin 7. A spring 9 bears against the'said support to retain same in position, the said support `being provided with a depending flange 8, which 'pears against the front edge of the bed-plate of the machine and acts'as a stop. W hen the device is not intended to be'used, the support 6 may be swung around upon its pivot 7 until it is at right angles to .the position in which it is shown, when the spring 9 will engage the end facefof an offset portion 10 of the support 6, the' spring then retaining the support in its out-of-use position. rl"he face of the support 6 is longitudinally channeled, and fitted to the said channel is a carrier 11. rlhe carrier acts as a support for a pin or stud 12, consti- 'tuting a locating means, as will presently be described. The pin or stud 12 is mounted on a plate 13, adjustably secured to the carrier 11 by means of a set-screw 14. The plate 13 is slotted, .so as to permitsome longitudinal adjustment of the locating means With respect to the carrier 11, supporting it. The carrier 1'1 is provided with a laterallyprojecting pin 15, arranged to enga-ge any one of a series of notches 16, formed as graduations of a scale denoted by reference character 1 7 as a whole. vThe carrier 11 has rigidly secured ,thereto a depending bolt or stud 1S, the lower'end of which carries a nut 19, between which and a washer 20, arranged against the under surface of the supportd, is locateda compressi'on-spring21. "the spring 21, which surrounds the stud 18, tends to holdthe carrier 11 down in its seat in the channel in the support 6 and to hold the pin 15 into engagement with one of the notches 16 of the scale 17. The bolt or stud 18 projects through a longitudinal slot 22 in the support 6, and so in no way impedes the free movement of the said carrier along its support. When it is desired to adjust the carrier along thel support from one position to another, the carrier is slightly lil'ted by pressing upward upon the bolt or stud 1S, thereby releasing the laterally-projecting pin l5 from the notch 16 with which it was in enpermits adjustment ol the locating means toward and away l'roni the work-clamp, so that the said locating-pm 13 may be properly positioned to present any predetermined size collar for a buttonhole-stitching operation. When the device is initially set in a machine, it is sometimes necessary. vto

compensate slightly for variations in width of bed-plate and in relative positions et the work-clamp with respect to the edge of the tirely immaterial, and in the present instance I have shown the ordinary form or' National work-clamp, employing a lower plate or work-support 23 and clamping-plate 24, supported by the forked presser-lever 25. For properly positioning the collar laterally I preferably provide a small angle-gage 26, secured to and carried by the plate 23, the

lower edge of. the collar being arranged to bear against the face of the said gage, as will be-readily. understood, in orderv to laterally position the collar, so that the buttonhole may be made the pro er distance trom the said lower edge. In Fig. 1 of the drawings a portion of the collar is shown in dotted outline in position for a buttonhole-sewing operation. One of the end buttonholes 4will be sccn as'engaged by the locating-pin 12 and the center of the collar in position in the work-clamp for a sewing operation.' It -will be readily seen thatby'causi-ng the locating means to actually engagethe end buttonliole of the collar mistakes iii positioning of the collar will be reduced to a minimum, it being only necessary to properly adjust 'the position of the locating-pin to insure proper posi- .tioning of the collar.

For di'll'erent classes 'of work I employ dif- For inferent forms of locating means. stance, where al button has been sewed to a 'fabric I may employ a locating means which will engage the said button and so properly position the fabric to Which it is attached for IOO IIO

another button-sewing operation or a buttonhole-sewing operation or any otheroper.-

ation that may be desired. In Figs. `5 and 6 I have shown a locating-plate 27 as. substituted 'for thelocating pin or stud 12, the locating-plate 27 being adjustably secured to the carrier 1,1 exactly as is the plate 13 of the locating means above described the said c f plate extending laterally for a short distance and then turning over and back again, so as to clear material passing between it, the end of the plate provided witha V-notcli 28 and adapted to engage a sewed button, as shown in Figs. 5 and 6.

I/Vhatl claim isf 1. In a gage for sewing-machines, tiiecombination with a support arranged to be sevnotches along one edge and having also a longitudinal slot therethrough, of a carrier fitted to said channel and arranged to slide longitudinally therein, said carrier provided with a laterally-e,Xtendmg 'finger arranged to regisy with a clamp, and meansfor adjustably seter with said notches, a dependent stud secured to said carrier and arranged to project through the slot in said support, a spring surrounding said stud, and arranged between an i abutment carrled by the stud and the lower surface of the said support, and a locatoieomprisin-g astud for engaging a collar-button and` a slotted plate to which said'studis attached, Said slotted plate adjustably secured to the saidl carrier by means of a clampingscrew engaging said carrier and 'assing through the slotted portion o'f the said plate.
